I've just watched the highlights of today's stage. I was a bit surprised at the inept way the Sky guys handled the finish!
Boom was holding his own in the group chasing the lone leader but had no team mates to help him, until, with just a few hundred metres to go, two Sky riders hit the front at speed, giving Boom the perfect lead-out, allowing him to catch the leader and putting him in position to claim the stage victory which seals the race for him. Then the Sky guys overdo the final corner with one of them smashing into a crash barrier!
With Thomas crashing badly earlier on, they haven't had a great tour.
